The Right Sub

I have almost made up my mind as to the Sub choice for my HT. Right now it's between the SVS PB!-ISD and the Paradigm PS1200. Compared to these guys does anyone else have any suggestions as to competitors? Any others I should look at and audition before I make my final choice? I am trying to stay at $600 or lower. I am just looking for the best BANG for my buck.

I recently heard the Rocket UFW-10 in Dallas and was very impressed. I did not have the opportunity to A/B this with anything else, but I think that it will provide very good value. The cabinetwork is first rate, but that may not be a value to you.

At a slightly lower price point, check out the Rava from Adire at $400.
